Scientists have embarked from Alaska on the second and final component of a NASA field campaign to study how changing conditions in the Arctic affect the ocean's chemistry and ecosystems. Phytoplankton will be a key focus of the campaign. While many algal blooms in the Arctic last just a few weeks, the bloom in Barrow Canyon last months. Scientists think the extended bloom can be explained by unique patterns in the path and timing of ocean currents. [Source: NASA News]
